Advanced LEDs Marlin Lantern Installations
The Advanced LEDs Marlin was the first LED PFI-compliant lantern to be manufactured entirely in the UK, around 2010. E.ON partnered with Advanced LEDs LTD to produce a low-energy lantern to light the UK's roads. This lantern bears a strong resemblance to the Advanced LEDs Clipper, which is a further-improved version of the Marlin released several years later. Thank you to AgentHalogen_87 for uncovering the information about these fixtures.

Column E2 on Rock Farm Road hosts several 35W Advanced LEDs Marlins.
The unique shape of the optics/reflector are visible clearly through the transparent lens. Ten large LED modules are also apparent.
I then followed Rock Farm Road and discovered more Marlins. Column E4 is pictured below:
This lantern was also photographed at night. The LEDs had aged, evident by the green hue which made them resemble MBF/U lamps.


The LEDs gave a great view of the sticker inside, providing more information about the lanterns. It appears that the colour temperature is was 6000K when they were new:
